Good choice for doubles
I'm using the JS12 for doubles and I prefer it over anything in the Yonex. The JS12 is aerodynamic and fast even on this 3U (88 grams) version. Well this is something special and not available in any of the Yonex. Try to stick to this 3U 88 grams as the lighter versions don't produce power very well. I'm not a physically strong player but this 3U 88 grams works well for me. I'd normally go for the lighter 4U 83 grams version but this racket in the 3U 88 grams is just nice for me.
